well guys here is my problem yesterday me and a buddy installed my sportlines on my 06 ls and there was no noises but today i had to run out and now i have a loud ticking noise in the rear i dont know what it could be from....i havnt got my alignment yett because its sunday and none of the tire places are open.has anyone herd of this before and i dont think its my new tires because i did some research on here and it seems like there is alot of ppl running 225/40/18...

 

is it just coming from one side and does the ticking change speed as the car does?

 

yea it sounds like its just one side and yea it gets faster when i go faster

 

ok, stupid question, but did you check to make sure it's not just a rock in your tire?

 

no dude its not a rock in the tire

 

Is it a ticking noise or more of a chirp. I lowered a friends ION quad coupe and the next he came back with a chirp noise over bumps and while driving turns out the noise was coming from the rear shocks.

 

this noise is there even if im driving on flat ground i donno its weird its like a clunking noise

 

well, if it's constant and changes speed as the car does, it's not the springs or shocks, it's something that is rotating. I'd just wait and see if it goes away when you get the alignment.

 

yea lets hope it do go away with the alignment im hoping so anyway

 

it has nothin to do with the alignment

 

yea the noise defently gets louder and faster as i speed up

 

Think about it.. It has to be something rotating.. If it gets louder as it speeds up.. The struts and springs don't rotate.. lol

Now, if it's a SQUEAK, yes, my factory rear struts/springs squeak ALOT.. I'll be curious to see if it stops after I install my Sportlines next week.. If not, then it's the struts..

 

oh i know its not the springs but i just dont know what it could be but ill find out today at 2!!!

 

Well, if you think about it, he's lowering an LS with sportlines. Drops 2.0 in the front and 2.5 in the rear. That big of a drop will noticeably affect the camber and will put rotating parts at an angle they shouldn't be at, which will be fixed with an alignment. The noise wasn't there before he did this and it changes speed as he does, so it is something that is rotating.

 

truth

 

tru tru but what i dont understand is that it wasnt there the day we installed them and i did a bit of driving around that day....it was the next morning when it started

 

it could have just taken that much driving for the clunk to start. let us know after your alignment, I hope it fixes it

 

Keep us updated. Getting my Sportlines in this week from CARLYLE, but I do figure I'll need to get an allignment shortly anyway..

 

well boys it was a stupid thing and its pretty much what i thought it was ......loose wheel because yesterday i was cleaning the rims and i hit 2 of the nuts and they were loose and i tightened them but it wasn't tight enough for it to stop the clunking but now im all good to go and she handels like she's on rails!!! and here is a pic of the car sittin all pretty

good thing that bitch didn't fall off

 

haha I drove back from Cleveland to Pittsburgh a few months ago on the highway for two hours with 3 lugnuts on each wheel.. lol. And I was supposed to have 5! I grabbed the wrong bag of lugnuts........ hahaha

 

Um no not true learn your car I do alignments all day the back is a solid axle it does not change the alignment angles in the rear when you lower a cobalt just the front

 

that's cool, you sound like a really smart guy. I was just telling him that if it started when he lowered it and it was constant with his speed, it has to do with rotating parts. It didn't make sense to me because the back is solid, but that was the only thing I could think of. My bad for trying to help the guy with inputs compared to "has nothing to do with the alignment" without giving any further information as to why. But good thing you're here, Mr. wheel aligner extremely hard job guy.

 

now now guys no need to be arguing it was a simple fix and i thank you for all the opinions!!!!

 

i wasnt, im glad you found it before it broke a stud or worse fell off. but enjoy the sportlines they rock thats what i had before the coilovers. if you pair them up with the konis, good god does the car handle.
